Yes, you got it. This looks like SUSE Linux.
To add it to the file of sound was right.

Hello!

On my Debian system there is no file named modprobe.conf. Instead
there is a directory named /etc/modprobe.conf with the following
files:

htpc:/etc/modprobe.d# ls -go
total 30
-rw-r--r-- 1  4360 2006-02-05 14:00 aliases
-rw-r--r-- 1 16153 2006-09-11 10:44 alsa-base
-rw-r--r-- 1   156 2005-12-16 10:05 alsa-base-blacklist
drwxr-xr-x 2  1024 2006-06-14 16:51 arch
lrwxrwxrwx 1     9 2006-06-14 16:51 arch-aliases -> arch/i386
-rw-r--r-- 1  1406 2006-02-20 16:15 blacklist
-rw-r--r-- 1   284 2006-02-20 16:15 display_class
lrwxrwxrwx 1    41 2006-10-15 20:07 linux-sound-base_noOSS ->
/lib/linux-sound-base/noOSS.modprobe.conf
-rw-r--r-- 1    29 2005-10-29 04:48 nvidia-kernel-nkc
-rw-r--r-- 1   363 2006-02-20 16:15 pnp-hotplug
-rw-r--r-- 1    61 2006-04-22 14:54 sound

The sound file contains what you told me to look for.

htpc:/etc/modprobe.d# cat sound
alias snd-card-0 snd-hda-intel
options snd-hda-intel index=0

After modifying this file as suggested I get:

htpc:/home/mythtv# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC880 Analog [ALC880 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: ALC880 Digital [ALC880 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

alsamixer now contains IEC958 which I toggled from <Off> to <On>.

htpc:/home/mythtv# lspci -s 00:10 -vn

What entries do I have to put in the ~/.asoundrc file?

I am not able to test if all this works until I get home. But it
surely looks very promising indeed.

Thanks for all the wonderful help!

Best regards,
Peter Carlsson
